AWS – Amazon VPC now supports multiple IPv6 CIDR blocks

Amazon Web Services (AWS) announces the launch of multiple IPv6 classless inter-domain routing (CIDR) blocks in a Virtual Private Cloud (VPC), enabling customer to attach up to 5 prefixes to their VPCs. Before today, customers could add up to 5 IPv4 CIDR blocks and 1 IPv6 block.
